Product Description

EXPANDAG is a soundless and safe demolition agent which is quite different from ordinary demolition agents such as explosives and dangerous materials. It does not cause any fly rock, noise, ground vibration, gas, dust or any other environmental pollution when used properly.

When it is mixed with clean and cold water to be mortar and poured into pre-drilling holes of rock and concrete, it swells and exerts expansive capabilities on the hole-wall at a unit value of more than 50Mpa (500kg/cm2. ) which is strong enough to cut and crack reinforced concrete, marble and granite after a while.

Copmare to the traditional explosives, it has the following advantages:
1)Non-explosive and very safe
2)very economical and cost-effective;
3)The shape is controllable

EXPANDAG can be applied to various situations:
1. Granite, marble, sandstone, limestone, quartzite quarrying and cutting
2. Precious stone quarrying
3. Rocks pre-splitting, fracture, cutting, demolishing and removal
4. Concrete structures demolition and rocks cracking when explosion not allowed
5. Fracture and demolition of the concrete buildings and structures
6. Rocks cutting for road construction.

As requirements for demolishing rock and reinforced concrete in construction increase in tight quarters, the use of explosives and explosive agents is becoming more restricted as far as safety and environmental pollution problems are concerned. EXPANDAG is your best solution.

EXPANDAG is a highly expansive powder designed for stone quarrying, mining, concrete cutting and demolition, etc. EXPANDAG expands when mixed with common water and poured into pre-drilled holes on stone or concrete. It produces an extreme pressure of 40-100 MPa (4000-10000 mt/sqm) on the hole-walls after a few hours reaction time in holes, while the tensile stress of stone and concrete is 3- 10 MPa (300-1000 mt/sqm), thereby crack them easily. EXPANDAG is environmental friendly and produces no noise, no vibration, no toxic gases, no flying debris or residue. It helps your work mmore efficient and cost effective.

EXPANDAG can be used in an almost unlimited range of applications. It's particularly used for breaking, cutting or demolishing stones, concrete and reinforced concrete. It is ideal for use in situations where surrounding buildings or other structures would be damaged by flying debris or vibration. It maximizes production time, product output and therefore profits, in quarrying and mining as it avoids waste of valuable stone.
